Configuring inbound MBGP route filtering

By configuring MBGP route reception filtering policies, you can filter out unqualified routes from an
MBGP peer or peer group.
Use the command...
system-view
bgp as-number
ipv4-family multicast
peer { group-name | ip-address }
default-route-advertise
[ route-policy route-policy-name ]
Use the command...
system-view
bgp as-number
ipv4-family multicast
filter-policy { acl-number | ip-prefix
ip-prefix-name } export [ direct | isis process-id
| ospf process-id | rip process-id | static ]
peer { group-name | peer-address }
route-policy route-policy-name export
peer { group-name | ip-address } filter-policy
acl-number export
peer { group-name | ip-address } as-path-acl
as-path-acl-number export
peer { group-name | ip-address } ip-prefix
